For inspiration, if not for direct usage, you might take a look at Jess. It's in Java, but the source is available. In particular, the language it uses has been tested and modified over time and may provide some ideas. Jess, like many other rules engines, implements the Rete algorithm, which seems to be the standard. There's also a (relatively) open process to make a standard API/library in Java for this.
